ClickHouse — what a crawler receives from clickhouse.com
Website measurement, not a product review. This page records what machine clients received from clickhouse.com. It does not evaluate ClickHouse software, features, pricing or support.
Answer engines can reach and read this site. It needs more it can quote.
AI visibility 76/100, measured 2026-10-11 18:10 UTC from outside its network, as each named AI and search crawler and as a browser. An engine can reach and read this site. What is left is giving it something specific to say.

The three stages, in the order an engine hits a site
Each stage gates the next. An engine that cannot reach a page never reads it; one that cannot read it never quotes it. That is why reach is a ceiling and not just a weight.
Stage 1 · 40% of the score
Reach
Can a named answer-engine crawler get your pages at all?
Every named crawler was served the same page a browser gets.
Stage 2 · 30% of the score
Read
Once it has the bytes, can it find the words?
The content is buried in markup, or the files that guide a crawler are missing.
Stage 3 · 30% of the score
Quote
Is there a specific fact it can state and attribute?
An assistant would have to paraphrase your page instead of quoting a fact.

The stage to fix first is quote, because the three run in order.
What to fix
5 findings on this site, 1 of them scored serious. Every one is named below; the top one is shown in full, free. What we saw, why each matters, how to fix it and the bytes behind it are what a licence buys — or we implement the whole list for you.

What we saw
2.5% of 350,763 decompressed bytes is visible text, and the largest single block is inline javascript at 86,311 bytes
Why it matters
A crawler pays for every byte it fetches and can only quote the text. Under 5% readable content means an answer engine downloads the whole page and comes away with almost nothing it can use — the difference between being quotable and being skipped. The content-ratio row above passes at 20%, so without this a page at 2% and a page at 19% were scored identically.
How to fix it
Move inline CSS and JavaScript into external files, drop unused page-builder styling, and make sure the words a visitor reads are in the HTML itself.
Developer: a template, theme or application change — a developer touches it
On Next.js (detected)
- Render content on the server: keep it in Server Components (the App Router default) or use getStaticProps / getServerSideProps; avoid "use client" at the page root and content fetched only in useEffect.
- Check View Source, not the browser inspector: the text must be in the HTML the server sends.

Get this fixed — $749The main product
We fix the 5 findings on clickhouse.com. $749, once.
1 of them are scored serious. One site. You keep the grade for free — this is the part where the list stops being a list.
- Every finding implemented on the site itself: machine files, schema, NAP, the lot
- An entity map authored for your business, not a template with the name swapped
- Measured again afterwards — the before and the after, sealed, so it is evidenced rather than claimed
- Thirty days of monitoring included
- Work starts within two business days
What it covers · one payment, nothing recurring
The chain a crawler follows
The chain breaks at entity graph. Everything after that point is only reachable by a crawler guessing the conventional path.
A machine file that does not parse is worth less than one that is absent, because it looks present. Rows behind this.
Where the bytes go
Of the 350,763 decompressed bytes the homepage delivers, 2.5% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 2.5% · 8,801 B
- Markup & attributes 36% · 126,299 B
- Structured data (JSON-LD) 0% · 147 B
- Inline JavaScript 56% · 196,371 B
- Inline SVG 5.2% · 18,342 B
- HTML comments 0.2% · 803 B
The individual blocks that weigh the most, so the fix is a search rather than a hunt:

If a reading here is wrong, it is our instrument that is wrong, and we want to know. Tell us what is wrong and the site is re-measured; the result is published as measured. Nothing about a listing, a payment or a request changes a number.
